Gun charges in New York that hinge on officer testimony often don’t lead to jury convictions. To change that, the city is pursuing an ambitious and expensive plan to collect and test DNA from every gun recovered to build cases based on physical evidence.
A California legislator will once again try to expand the collection of DNA evidence in criminal cases, which has declined under Proposition 47’s reassignment of some former felonies to misdemeanor status.
The controversy concerns TrueAllele, a genotyping program used to identify suspects in complex DNA mixtures involving more than one person. Just five of the country’s 250 crime labs use the program, which is central to a legal fight in New York.
